Lab Framework

HTML5-based open source scientific models, visualizations, graphing, and probeware from the Concord Consortium. This framework is deployed in the following places. These sites contain many examples of what it can do:

Setup Development


Setup the local Lab repository for development

  1. Clone the git repository
  2. cd lab
  3. make everything
  4. open another new terminal and run rackup
  5. open http://localhost:9191
  6. (optional) open a new terminal and run guard

It is recommended that you review the initial setup details. They describe what each of the steps above does.

Contributing to Lab

If you think you'd like to contribute to Lab as an external developer:

  1. Create a local clone from the repository located here: This will by default have the git-remote name: origin.

  2. Make a fork of to your account on github.

  3. Make a new git-remote referencing your fork. I recommend making the remote name your github user name. For example my username is stepheneb so I would add a remote to my fork like this:

    git remote add stepheneb
  4. Create your changes on a topic branch. Please include tests if you can. When your commits are ready push your topic branch to your fork and send a pull request.

Automated Browser Testing

Lab framework tests are automated using open source support from BrowserStack and SauceLabs.

For more information, please visit lab-selenium-tests repository.
